LEXSY Background Information

  
Leishmania tarentolae, a unicellular, flagellated protozoan organism, belongs to a family of parasites shuttling between sandflies and vertebrates. Since isolation from its host Tarentola mauretanica in 1921, L. tarentolae is kept in axenic culture, and it is not pathogenic to mammalians. The LEXSY expression strains are therefore grown under S1 laboratory safety conditions.

LEXSY strains can be handled like E. coli: they may be grown on agar plates or in liquid media from 96-well plate up to fermenter format. They have doubling times as short as 4 hours under optimum aeration and grow to high density within short time.

Why did we develop LEXSY and how does it compare to other available expression systems? What are LEXSY's main advantages?

The LEXSY host vector systems allow the constitutive or inducible, cytoplasmic or secretory expression of target proteins:
